Motor prediction reduces beta-band power and enhances cerebellar-somatosensory connectivity before self-touch to enable its attenuation

The paper shows that motor prediction reduces beta-band power and increases cerebellar-somatosensory connectivity before self-touch, enabling its sensory attenuation.

Predictions of bimanual self-touch determine the temporal tuning of somatosensory perception

The paper shows that perceived touch intensity decreases during hand reaching movements toward self-touch and recovers afterward, highlighting the role of motor predictions in somatosensory perception.

Divisive attenuation based on noisy sensorimotor predictions accounts for excess variability in self-touch

The paper develops a computational model explaining why self-generated forces are perceived as weaker, showing that attenuated sensations have greater variability due to added motor prediction noise.

Dynamic changes in somatosensory and cerebellar activity mediate temporal recalibration of self-touch

The paper investigates how the brain recalibrates temporal expectations for self-touch through dynamic changes in somatosensory and cerebellar activity.

Action does not enhance but attenuates predicted touch

The paper demonstrates that action attenuates rather than enhances predicted touch, challenging recent theories that propose the opposite.

Aging exerts a limited influence on the perception of self-generated and externally generated touch

The paper investigates whether aging increases somatosensory attenuation and finds no significant increase in elderly participants, challenging previous claims of a direct relationship.

Brief temporal perturbations in somatosensory reafference disrupt perceptual and neural attenuation and increase supplementary motor-cerebellar connectivity

The positive dimension of schizotypy is associated with a reduced attenuation and precision of self-generated touch

This study finds that higher positive schizotypal traits are linked to reduced somatosensory attenuation and precision for self-generated touch.

Predictive attenuation of touch and tactile gating are distinct perceptual phenomena

The paper distinguishes between predictive attenuation and tactile gating as separate perceptual phenomena by showing they operate independently and are not correlated.

No evidence for somatosensory attenuationduring action observation of self-touch

The paper tests whether observing self-touch actions leads to somatosensory attenuation, finding no evidence for it, suggesting the mirror neuron system does not automatically simulate observed actions.

Efference copy is necessary for the attenuation of self-generated touch

This study tests whether efference copy is necessary for somatosensory attenuation of self-generated touch, finding that voluntary movement, not passive movement, leads to reduced perceived intensity.

Functional connectivity between the cerebellum and somatosensory areas implements the attenuation of self-generated touch

The paper investigates how cerebellar connectivity with somatosensory areas correlates with the perception of self-generated touch attenuation in humans.

Rapid learning and unlearning of predicted sensory delays in self-generated touch

The paper shows that people can rapidly unlearn to reduce the intensity of self-generated touch and learn to reduce delayed touch after repeated exposure to a systematic delay.
